* Fixed read-after-free bug found by TSAN in StorageServer.cpp
* Fixed write-after-free bug found in UbaProcess.cpp (m_cancelEvent.Set() could be called after memory was freed)
* Lots of minor fixes found using TSAN. Most are harmless but still nice to cleanup
* Disabled mimalloc for linux again.. seems like tsan does not like it so maybe there are bugs in it

* Changed so ClientSession struct is allocated using aligned_alloc instead of new.. we can't figure out why this is failing with new on the farm and noone can repro so this is a very nasty workaround until we do understand how it can go wrong.
* Fixed potential race condition in scheduler
* Reduced lock scope in StorageClient to remove chance of deadlock
* Enabled mimalloc on linux

* Turned off mimalloc again for linux because of new errors not seen before
* Improved some error descriptions and bumped error stack buffer a bit
[CL 31373146 by henrik karlsson in ue5-main branch]
* Added hint to unmapfileview to be able to add useful information to asserts on fails
* Added error handling for vsnprintf returning error
* Fixed memory stomp in unit test
* Removed usage of %hs on non-windows since asan complains about it
* Changed UBA_USE_MIMALLOC to always be defined and be 0 or 1 instead of using ifdef
* Enabled mimalloc on linux
